I disagree with the notion that all of them come from the same archetype, or that which archetype they fall into is a matter of opinion... unfortunately, the comics do tend to stick to certain 'types' over the decades when tackling these characters, so they can be at the very least be categorised. Bane will still be the hulking brute/doomsday monster no matter how intelligent he is. The trick for Nolan or anyone writing Batman would be to round-off that archetype in a way that the character--within the context of the story-- isn't reduced to it.
